“…A study found that the shoulder area generally has lower temperature generation than the pin area, despite its dominant role in workpiece temperature generation [94]. A study linked the tool contact pressure to process void defects and observed a decrease in tool service life with increasing the tool rotational speed [95]. The study tested tool eccentricity and welding speed on three eccentric points (0, 0.2, and 0.8 mm) for constant rotation at 600 rpm and varying welding speed from 100 to 500 mm/min, determining maximum joint strength [96].…”

“…Similarly, Su et al [14] multiplied a temperature-dependent empirical factor to the Sellars-Tegart model to describe the yield strength. Shi et al [16] studied the formation of void defects in friction stir welding by multiplying the Sellars-Tegart model with an empirical factor related to the solidus. Geng et al [17] described the high-temperature softening behavior of metals by multiplying a temperature-dependent power empirical factor on the Jackson-Cook model, which is aimed at studying the influence of rotating tools on the formation and microstructure of aluminum and steel lap joints in friction stir welding.…”

In advanced solid-state manufacturing processes such as friction stir welding, the metal’s temperature ranges from room temperature to the solidus temperature. The material strength in the temperature range is generally required for investigating the mechanical behaviors. In this communication paper, an analytical model is proposed for describing the thermal softening of aluminum alloys for room temperature to solidus temperature, in which the concept of temperature-dependent transition between two thermal softening regimes is implemented. It is demonstrated that the proposed model compares favorably to the well-known Sellars–Tegart model and Johnson–Cook model. The constants of the proposed model for nine typical engineering commercial aluminum alloys are documented.
